Revision 04 - 24 January 2019
1 DESCRIPTION AND OPERATION
The device Vega TD-11 is designed for measurement atmosphere temperature (air and
non-aggressive gases) by the external thermistor and further transmitting of this data to the
LoRaWAN network.
Also, device can act as a security sensor and send extraordinary alarm message by the
triggering security input.
There is a function of temperature range control in the device. During device setting,
you may set allowed temperature low and high thresholds. When temperature measurements
are out of specified temperature range then extraordinary communication session appears.
Data collection periods when measurements in temperature range and out are set
independently.
Vega TD-11 may be used in systems where temperature control is required but its
directly measurement is difficult. For example, car engine temperatures control and
temperature control at the production rooms, stocks.
TD-11 is powered by a 3400 mAh built-in battery with service life up to 10 years,
provided data transmitted once a day.
The device is powered by a non-rechargeable lithium-thionyl chloride
(LiSOCl
2
) battery
Attempts to charge the battery may result in fire
COMUNICATION AND DATA COLLECTION ALGORITHM
The readings collecting from the thermistor with a configurable period from 5 minutes
to 24 hours. The readings stored in the device memory and transmitting during the next
communication session with the LoRaWAN network.
